Problems solved by technology

However, these devices are not compatible with the standard 95 KHz public broadcast protocol.
Moreover, the devices that are compatible with the 95 KHz public broadcast standard are not compatible with the 2.3 MHz and 2.8 MHz systems.
Moreover, there are currently no IR listening devices on the market that are capable of being connected to a telephone line and that can give notification to a user of incoming telephone calls while they are listening to an audio program with the devices.

Embodiment Construction

[0017]FIG. 1 is an upper, right side and front perspective view of an exemplary embodiment of a wireless listening system 10 in accordance with the present invention, showing a wireless headset unit 12 of the system docked in an associated base unit 14 thereof. The listening system 10 is intended for the hard-of-hearing, and accordingly, the amplified headset 12 and a base 14 are specifically designed for transmission and reception of infrared signals for the purpose of reproducing sound generated from home stereos, televisions, computers, and the like, as well as public address systems, such as theaters, auditoriums and other public sound sources, while also providing the ability to alert the user to an incoming telephone call. The system is thus designed as a consumer electronic solution for those who experience a mild-to-severe hearing loss who wish to experience both public and private sound broadcasts.

[0018]The base unit 14 of the exemplary system 10 is illustrated in the upper...

Abstract

A wireless listening system includes a base operable to receive an electrical signal corresponding to an audio signal, including the ring of an incoming telephone call, up-convert the audio signal to an infrared signal, and transmit the infrared audio signal wirelessly therefrom, and a wireless headset operable to selectably receive either the infrared audio signal transmitted by the base, or an infrared signal corresponding to an audio signal transmitted by a public address system, down-convert the received signal back into the audio signal, and audibly reproduce the audio signal to a wearer of the headset. The system enables a hearing impaired listeners to enjoy their favorite audio programs without disturbing nearby persons with normal hearing and without missing an incoming telephone call, and is also compatible with public IR PA systems currently used to assist the hearing impaired community.

Description

BACKGROUND[0001]This disclosure relates to wireless communication systems in general, and in particular, to wireless listening systems for the hard-of-hearing that use infrared signals to enable such users to hear and better understand the sound from home stereos, televisions, computers, public address systems, theaters and the like, while also providing the ability to alert the user to incoming telephone calls.[0002]Nearly 34 million Americans are affected by a hearing impairment that is sufficiently profound as to prevent them from enjoying television, music and other audio program broadcasts. In addition to private settings in which the hard-of-hearing may not be able to hear sound broadcasts adequately, this segment of the population may also be excluded from hearing in public meetings, church services or theater events and the like.[0003]There are currently a number of personal sound amplification devices on the market that amplify sounds from stereos, televisions and computers...
